“…These features seem to cut Gorce Mts. ; this is not confirmed by our other studies (Kania and Szczęch, 2020;Szczęch and Cieszkowski, 2021). Further to the north, these two lineaments are delimiting massifs of the Beskid Wyspowy Mts.…”

“…Our previous study (Kania and Szczęch, 2020), based on the interpretation of the model augmented with field geological mapping (Szczęch and Cieszkowski, 2021), showed how a lineament network can be interpreted in topological and geometrical terms. The aim in the present paper is to up-scale DEM-based geometrical and topological analyses of a regional scale lineament network to find how this is reflected in the tectonic structure of the Western Carpathians.…”

Abstract. The Polish part of the Western Outer Carpathians lineament network was analysed based on the GMTED2010 digital elevation model. Lineaments were identified in the visual screening of the hillshade model. To the best of our knowledge, no one has studied the geometrical properties of the network with relation to the topological ones. The NetworkGT QGIS toolbox was applied to identify the nodes and branches of the network, as well as to calculate the topology parameters. Our aim was to find differences between the western and eastern parts of the Western Outer Carpathians; therefore, the analyses were carried out in six sectors chosen based on the geographical subdivision in the geological context: three in the north, mainly the Silesian unit; and three in the south, mainly the Magura unit. We found general agreement of the identified network with the photolineament map; however, some of the photolineaments are not confirmed by digital elevation model (DEM). We found that the topological parameters of the networks change from west to east, but not from north to south. There are areas of increased interconnectivity, especially the Nowy Sącz Basin, where the lineament network may reflect a complicated system of cross-cutting deep-rooted fault zones in the basement.

“…Denivelation in the area, measured in a grid 1 × 1 km are between 100 m in the external part of the massif and 400 m in its central part. Morphology is mainly related to the bedrock composed of flysh (sandstones, shales) deposits and geological structure (Szczęch et al, 2016; Szczęch & Cieszkowski, 2021; Szczęch & Waśkowska, 2023). Resources of groundwaters are of good quality and mainly related to the fissured flysh sediments of Magura Beds Basin and sand‐gravel cover (Żaczek & Porowski, 2017).…”

The grasslands which are an important part of an ecosystem are endangered due to abandonment of traditional forms of land use. Preservation of biodiversity of semi‐natural grassland communities is of great importance, therefore it is important to identify threats and prepare a sustainable plan for their protection The goal of this study was to develop an approach to predict threatened grasslands hotspots, basing on multi‐factor machine learning analyses. The Gorce Mountains in the Polish Carpathians were chosen as a study area, as it is region partially protected by National Park, surrounded by villages with different socio‐economic conditions (agriculture or touristic oriented). The grasslands were identified and classified on Sentinel‐2 multispectral imagery. As lack of regular mowing of grasslands was found as main factor promoting forest succession. Therefore, in order to find endangered grasslands areas, support vector machines' algorithm was used to classify them in mowed and unmowed categories. Then the preservation potential of grasslands was modeled with the random forest method, based on the grasslands' mowing classification, digital terrain model, land‐use and population statistical data, and the historical forest extent. We found the grasslands above 750 m above sea level to be the most endangered. Also, the tourism activity and ongoing changes in employment structure from agriculture to services has had a negative influence on the grasslands preservation potential. On the other hand, the Gorce National Park's active grassland conservation by mowing and grazing was shown as a positive element in keeping with the high biodiversity of the area.

The lithological characteristics and age analysis of the variegated Farony Shale are presented for the first time. The Farony Shale occurs in the Lubomierz and Rabka areas in the Bystrica Subunit. It is located within medium- and thin-bedded sandy dominated turbidites of the Campanian–Paleocene Ropianka Formation. It is comprised of red shales laminated or interlayered with strongly bioturbated green shales. Exposures of the Farony Shale are observed along a distance of ~25 km, in the form of a narrow belt. The age of the variegated deposits is estimated based on agglutinated foraminifera to late Campanian–earliest Maastrichtian. Their deposition was associated with low-energy conditions and a temporary limitation of the supply of sandy material to the inner part of the Magura Basin.
